Agreed, 6.8 won't scratch the big bore itch. Tromix has a 375 SOCOM now as well. I'd look to him for a upper and be done. Just do your research of you end up SOCOM. About half the manufactures use the reverse engineered reamer and have had issues reported with factory ammo.
Or, you could scratch both itches and get s 358 win AR-10.
